2  Product Overview

2.1  Introduction

The RPS1000-A3 is an external power supply unit that uses AC inputs and provides eight lines of DC output, with a maximum output power of 2900 W. It can provide DC power supply simultaneously for multiple powered devices (such as switches and routers). The RPS1000-A3 can serve as:

l       A heavy-duty external PoE power supply unit

l       A redundant backup power supply unit for the powered devices

When serving as a redundant backup power supply unit, the RPS1000-A3 has the following functions:

l       If using the same AC power source with the powered device, when the internal power supply system of the powered device fails, the RPS1000-A3 can provide DC supply to the powered device, thus ensuring uninterrupted operation of the powered device;

l       If using the different AC power source from the powered device, when the AC power source to the powered device fails, the RPS1000-A3 can provide DC supply to the powered device, thus ensuring uninterrupted operation of the powered device.

Note:

The RPS1000-A3 supports hot backup of power supply. Namely, when the power supply system of the powered device operates normally, the RPS1000-A3 also provides part of the power supply to the device; when the power supply system of the powered device fails, the RPS1000-A3 becomes an independent power supply system.
